Heroku Kong Buildpack support

Hi Team, We have few APIs in Heroku and wanted to leverage Kong API gateway for the same. It looks like, current support for Heroku kong is halted (https://github.com/heroku/heroku-kong) and (https://github.com/heroku/heroku-buildpack-kong). I would like to know what will be the future of this project. Also if it is discontinued how we will support Kong on Heroku. Your help will be appreciated.
